Question

The consistent reduction in fitness (survival, reproduction, etc) in a population due to widespread non-random mating is called ____________________.

Answer 1

Answer:

Natural selection

Explanation:

Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that it is able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
